T b, all w from it on 04/ concern Beit; known that I, Jason I. Rosin, a citizenot the United States. of America, residing at New; York, inthezcounty' of New 5 Yorkand StateofNewQXorlnhaive invent ed certain new. and. useful, Improvements in Gas Burners, of which. the following is a specification.

Thepresent, invention relates to burners,

particularly. gas, burners, and, has for its principal object toprovide a new and improved burner which will be, simple and durable in construction; and which, with. a

comparatiyely small amount, of fuel, will produce.anintenselfiame which can be ad} va'ntageously used for the; production of brilliant incandescent. light, forheating' purposes, soldering, etc. V f

With this ob'ect in view, my invention consists substantially-.- in a Bunsen burner and a conducting tube formed with a, comparatively large air or, mixingchamber intersecting the fiowofithegasmixture above the nozzle of the Bunsen burner, whereby a perfectly blue flame of intense heat is produced at the end of the conducting tube.

My invention also consists in the novel construction arrangement and combination of parts as will be hereinafter more fully described and defined in the appended claims.

In the accompanying drawing which forms part of this specification and in which similar reference characters denote corresponding parts, Fig. 1 is a vertical section of my new burner; Fig. 2 is a cross section on line 2-2 of Fig. 1; Fig. 3 is a vertical section of a modified construction; Fig. 4:, a cross section on line 4c4: of Fig. 3; Fig. 5

is a vertical section of another modification, and Fig. 6 is a cross section on line 6-6 of Fig. 5. I Referring to the drawing more in detail, and first to the construction shown in Figs.

4 l and 2, a denotes the Bunsen burner which may be of usual construction and b, the conducting tube mounted over the nozzle (1 of the Bunsen.

This conducting tube is composed of two longitudinal sections 6, 6 between which is inserted a hollow body 0 toserve as an air chamber. The body 0 is composed of two substantially conical sections 0', 0 mounted on one another with their larger diameters and joined together to form a single piece.

On to ,and bottom'the body a is provided wlth s ort cylindrical necks c e adaptedflto. engage..the pipe'sections b, 6?. In, the upper, section 0 of the-body 0 I provide. a' .plu-f ralityj of air openingsd. ando'ver the inner,

face of said section is mounted-a piece of wire netting. or, gauze ej to cover said open? ings. k The pipe sectionsb, b? are,.adapted to be adjustablerelative toQone another so that the free spaceflwithin the chamber c between the opposite ends of sections; may bel-eii' e larged or reduced in, order to regulatelthe quantity ofair desired to be. added to the gas mixture flowing from the, bun'sen through the conducting tube. f l

.As themixture rises in the tubeand burns at. the free end of. the'se'ction airis being sucked into the chamber 0 through its open ings d which mixes withfthe burning mix} ture and, owing tothemapid supply, of oxy gen, produces a flame otintense; heat, i

By enlarging the space between theopposite ends of the pipe sections 6, b the quantity of air to be added to the mixture issuing from the Bunsen burner may be regulated according to the intensity of the heat desired.

A burner of this construction may be used in lieu of a blowpipe, thus dispensing with bellows or other means for producing air currents.

The construction just described may be variously modified. Thus, in Figs. 3 and 4, the chamber 7 is shown in form of a bell,

inserted between the sections g, 9 01 the pipe h. I

The mouth portion of the bell is apertured and covered with gauze or wire netting i. The pipe sections 9' g are adjustably mounted in the central neck portions f, f of the bell in a similar manner as in the first described construction.

In the modification according to Figs. 5 and 6, the conductin tube 7' is made as a continuous piece whic on its circumference intermediate its ends, is provided with longitudinal recesses 70. The bell-shaped body Z is formed centrally with an inwardly projecting sleeve-shaped portion m which fits over the tube.

The openings 7c and the sleeve m are so admeasured relative to one another that according to the position of the hell on the tube the sleeve m may obstruct the openings ters 'Patent is:

1. A gas burner comprising a bunsen, a conducting tube composed of two superposed and separated sections and a mixing chamber between said sections, said mixing chamber having air holes arranged at an angle to the central vertical axis thereof, so that the air drawn into said chamber during the flow of the gas will be directed into the path of the latter and thereby become thor oughly mixed therewith before passing into the upper section of the conducting tube.

. 2. In a gas burner, a bunsen, a conducting tube composed of two superposed and separated sections and a mixing chamber interposed between said sections, said mixing chamber having its upper part made in form of a converted cone formed with a plurality of air holes, so that the air drawn into said chamber during the flow of the gas will be directed into the path of the latterand become thoroughly mixed with it before passing into the upper section of the conducting tube.

3. In a gas burner, a bunsen, a conducting tube composed of two superposed and separated sections, and a mixing chamber interposed between said sections, said sections being adjustable relative to one another and to said mixingchamber and the latter having a plurality of openings arranged at an angle to the central vertical axes thereof so that the air drawn into said chamber during the flow of the gas will be directed into the path of the latter and becomethoroughly mixed with it before passing into the upper section of said conducting tube.

4c. In a gas burner, a bunsen, a conducting tube composed'of two superposed separated sections and a mixing chamber between said sections, said sections being adjustable relative to one another and to said mixing chamber and the latter being formed with perforations in its upper part arranged at an angle to the central axis of said chamber and a lining of wire netting covering said JACOB I.
